From publisher Wellcome Trust and developer Toytek comes Filth Fair, a word-based puzzle game for the iPhone and iPad.

The Filth Fair has you select objects from a painting and then solve a word puzzle based on that object. As the game's title suggests, the main theme here is filth, so each word has something to do with dirtiness, evil, ill morals or other general nastiness. The painting consists of a fair ground covered with animals, such as bears, elephants, pigs, cows and iconic characters, such as Adam and Eve. All together, there are over 331 different words to find, since each object in the game has more than one word associated with it.

The game offers help in the form of a cryptic clue and hint. You can also earn "Wild Stars" which reveal hidden letters. As you play and successfully solve the jigsaw word puzzles, you'll earn medals and eventually the grand trophy.

Thus far, the game is enjoying positive user reviews – with an average rating of 4 stars on the App Store.

You can download and play The Filth Fair for free on the iTunes App Store.
